An alternating current varying sinusoidally has a peak value of 50 A and a frequency of 10 Hz Mathematical expression for the current is:
1
i = 50 * √2 sin (2 * π * 10)t
2
\(i = \frac{{50}}{{\sqrt 2 }}\sin \left( {2*\pi *10} \right)t\)
3
\(i = 50*\sqrt 2 \sin \left( {\pi *10} \right)t\)
4
i = 50 sin (2 * π *10)t
